System Backup

10.3.2 Outline
The automatic backup function saves the internally stored data in a single file in advance
for the smooth restoration from unexpected troubles of the YRC1000.
The teaching operation is one of the factors that changes the internally stored data. Thus,
a mode which backs up the latest data after the teaching operation is prepared. To confirm
the termination of the teaching operation, check the mode key whether it is changed from
TEACH mode to PLAY mode.
Other than the teaching operation, the present position of the robot or the value of a variable
can be pointed out as the factors to change the internally stored data. These data, however,
are changed after each operation and have very little need to be retained permanently.
Accordingly, backing up these data at regular interval should be well enough to operate and
the mode to back up the data at regular interval is also prepared.
Furthermore, the mode to back up the data when starting up the YRC1000 and when
inputting signals are also available for some specific versions.
With the automatic backup function, all the part where the internal data is stored in the
physical memory area is collectively saved. If there is any data which is in the middle of
changing while executing the automatic backup function, the data might not be usable for
restoration because of its inconsistency. Therefore, the function is terminated with an error
during the play back operation or while the robot is in motion so that the automatic backup
can not be operated. Set the automatic backup function to be executed while the robot is
not in the playback status and while the robot is stopped.
The automatic backup function has the following functions and features:

Function / Feature Explanation
1 Cyclic backup:
In the teach mode, the data in memory
is backed up in a specified cycle from a
specified starting time.
This function backs up as much of the lat-
est data as possible during editing.
The backup data saved in theSD card can
be loaded to the YRC1000 in case of data
loss so that the damage can be mini-
mized.
2 Backup when switching modes:
When switching the mode from the
TEACH mode to the PLAY mode, the
data in memory is backed up.
The editing data is backed up when edit-
ing is completed.
The latest data is automatically backed up
with this mode.
3 Backup when start-up:
When the YRC1000 is start-up, the
data in memory is backed up.
When the YRC1000 starts up, the data in
memory is backed up.
Since the editing/playback operation is
usually completed when the robot control-
ler power is turned OFF, the latest data is
automatically backed up with this mode.
4 Backup when inputting specified sig-
nals:
The data in memory is backed up when
a specified signal (#40560) is input.
The data in memory is backed up by the
signal from the host at the intended tim-
ing.
Although the above mentioned items 1 to
3 are designed to back up the data auto-
matically, this function backs up the data
in accordance with the instruction from the
host.
